I have a website with multiple subdomains, which share a unique PHP session cookie to identify each user. I did this by simply adding
session.cookie_domain = '.mydomain.com', however I’m wondering if it’s possible to specify more than one subdomain, so that cookies will only get sent to, for example,
user.mydomain.com but won’t in
Would this be possible?
No, those would have to be 2 separate cookies.
You would have to create a sub-domain like
sub.mydomain.com, have hosts like
www.sub.mydomain.com etc., and set cookies for
.sub.mydomain.com if you wanted to isolate cookies in that way…
for future users, actually you can just rename the cookie id and you can have specific cookie for that subdomain
